The present invention furthermore relates to methods for selectively controlling herbicidal plant growth in crops with these herbicides.

The literature discloses thiochromenones of the formula I in which at least one of the radicals R¹, R² or R³ is substituted amino, having a pharmaceutical action (EP-A 159,964, GB-A 2,014,991). Furthermore, the preparation of the thiochromenones of the formula I is described in a publication by Bosserr et al. (Ann. Chem. 680 (1964), 40 et seq.).

However, the stated publications do not describe any antidote or antagonistic action of the known compounds in combination with herbicidal active ingredients.

It is an object of the present invention to provide herbicides which ensure good control of undesirable plants without significantly damaging the crops or substantially reducing their yield at harvest.

We have found that this object is achieved by the herbicides defined at the outset.

We have also found methods for treating crops with the antagonistic compounds I and the herbicides II or herbicides III, whether the compounds I and II or I and III are formulated and applied together or separately, and the order of application in the case of separate application, being unimportant.

The herbicides contain at least one antagonistic compound I and at least one herbicide II or one herbicide III.

However, further antagonistic or herbicidal compounds may be present in the novel herbicides.

The substituted thiochromenones of the formula I are suitable as antidotes for improving the toleration of herbicidal active ingredients by crops such as millet, rice, corn, cereal species (wheat, rye, barley and oats), cotton, sugar beet, sugar cane and soybean. They have an antagonistic effect on herbicides from a very wide range of classes, such as triazines, phenylurea derivatives, carbamates, thiocarbamates, haloacetanilides, benzoic acid derivatives and in particular halophenoxyacetates, substituted phenoxyphenoxyacetates, phenoxyphenoxypropionates and cyclohexenone derivatives.

Herbicidal cyclohexenone derivatives II are disclosed in, for example, EP-A 228 598, EP-A 230 235, EP-A 238 021, EP-A 368 227, U.S. Pat. No. 4,432,786, DE-A 24 39 104 and DE-A 38 38 309. They are used predominantly for controlling undesirable grasses in dicotyledon crops and in grasses which do not belong to the Gramineae family. Depending on the substituents and the dosage of the compounds of type II and their use, these cyclohexenones can also be employed for selectively controlling undesirable grasses in gramineous crops, such as wheat and rice.

Further cyclohexenone derivatives II can be prepared in a conventional manner by synthesis methods known from the literature (cf. for example EP-A 169 521), for example by reacting triketones IX (disclosed in, for example, EP-A 80 301, EP-A 125 094, EP-A 142 741, U.S. Pat. No. 4, 249,937, EP-A 137 174 and EP-A 177 913) with hydroxylamines X (disclosed in, for example, Houben-Weyl, Methoden der Organischen Chemie, Volume 10/1, page 1181 et seq.): ##STR5## Advantageously, the reaction is carried out in the heterogeneous phase in a solvent, preferably in the presence of a base, the hydroxylamine preferably being used in the form of the ammonium salt.

Examples of suitable bases are the carbonates, bicarbonates, acetates, alcoholates and oxides of alkali metals and alkaline earth metals, such as sodium hydroxide, potassium hydroxide, magnesium oxide and calcium oxide, as well as organic bases, such as pyridine, and tertiary amines, e.g. triethylamine.

The triketone and hydroxylamine are preferably used in about stoichiometric amounts. The amount of base is not critical but is usually from about 0.5 to 2 mol equivalents, based on the amount of IX.

In general, the reaction temperature is from 0° C. to 80° C.

Examples of suitable solvents are dimethyl sulfoxide, alcohols, such as methanol, ethanol and isopropanol, aromatic hydrocarbons, such as benzene and toluene, chlorohydrocarbons, such as hexane and cyclohexane, esters, such as ethyl acetate, and ethers, such as diethyl ether, dioxane and tetrahydrofuran. The reaction is preferably carried out in methanol, using sodium bicarbonate as the base.

The reaction is complete after a few hours. The product II can be isolated, for example, by evaporating down the mixture, partitioning the residue in methylene chloride/water and distilling off the solvent under reduced pressure.

However, the free hydroxylamine base can also be used directly for this reaction, for example in the form of an aqueous solution; depending on the solvent used for the hydroxylamine X, a one-phase or two-phase reaction mixture is obtained.

Suitable solvents for this variant are, for example, alcohols, such as methanol, ethanol, isopropanol and cyclohexanol, aliphatic and aromatic hydrocarbons and chlorohydrocarbons, such as hexane, cyclohexane, methylene chloride, toluene and dichloroethane, esters, such as ethyl acetate, nitriles, such as acetonitrile, and cyclic ethers, such as dioxane and tetrahydrofuran.

No special conditions are required with regard to the pressure; the reaction is therefore usually carried out at atmospheric pressure.

Alkali metal salts of the compounds II can be obtained by treating the 3-hydroxycompounds with sodium hydroxide,. potassium hydroxide or a sodium or potassium alcoholate in aqueous solution or in an organic solvent, such as methanol, ethanol, acetone or toluene.

Other metal salts, such as manganese, copper, zinc, iron, calcium, magnesium and barium salts, can be prepared from the sodium salts in a conventional manner, as can ammonium and phosphonium salts by means of ammonia or phosphonium, sulfonium or sulfoxonium hydroxides.

The compound of type IX can be prepared by known methods (Tetrahedron Lett. (1975), 2491), for example from the corresponding cyclohexane-1,3-diones of the formula XI ##STR6## It is also possible to prepare the compounds of the formula IX via the enol ester intermediates, which are obtained in the reaction of compounds of the formula XI with acyl chlorides in the presence of bases and are then subjected to a rearrangement reaction with certain imidazole or pyridine derivatives (Japanese Preliminary Published Application 79/063 052). ##STR7## The hydroxylamines of the formula X are obtained, as a rule, by a number of known process steps starting from known intermediates: ##STR8## L=Hydroxyl or a leaving group, for example halogen, such as chlorine, bromine or iodine, or CH₃ SO₂ --O--.

The alkylating agents required for synthesizing the hydroxylamines X are known from the literature or can be prepared by known methods.

Syntheses of derivatives in which W is an aliphatic or olefinic chain which may be interrupted by hetero atoms are described in the following publications: DE-A 3 437 919; Tetrahedron Lett. 28 (1979), 2639; Org. Synth. Coll. 1 (1944), 436; DE-A 2 654 646; DE-A 2 714 561; J. Org. Chem. 52 (1987), 3587; DE-A 948 871; DE-A 948 872; J. Med. Chem. 26 (1983), 1570; Synthesis (1983), 675; J. Org. Chem. 48 (1983), 4970; Org. Synth. Coll. Vol. V, 249; EP 48 911; EP 143 952; U.S. Pat. No. 4,686,735.

For the preparation of compounds II in which W is an aliphatic or olefinic chain and R^(f) is a heterocyclic structure, reference may be made to the following literature: J. Heterocycl. Chem. 14 (1976), 525; JP 55 051 004; JP 55 047 601; Houben-Weyl: Methoden der organischen Chemie Volume 4/3, page 424 et seq.; DE-A-2 821 409; Chem. Ber. 114 (1981), 3667 and 3674.

Preparation methods which start from suitable carbinols XII (L=OH) are disclosed, for example, in: Tetrahedron 35 (1979), 329; Chem. Lett. (1977), 423; Houben-Weyl, Methoden der organischen Chemie, Volume 13/9B, page.964 et seq., ibid. Volume 5/3, pages 862 and 899 et seq.; ibid. Volume 5/4, page 361 et seq.

The preparation of alkylating agents in which W is substituted or unsubstituted C₃ -C₆ -alkynyl can be carried out by classical methods (cf. J. Med. Chem. 29 (1986), 1389; ibid. 24 (1981), 678; EP-A 131 320; J. Chem. Ecol. 10 (1982), 1201) or by coupling 1-alkynyl derivatives to aryl or hetaryl halides in the presence of palladium catalysts (cf. for example Tetrahedron Lett. 50 (1975), 4467).

XII is coupled to a cyclic hydroxylimide XIII and the resulting protected hydroxylamine derivative XIV is cleaved to give the free hydroxylamine X, preferably with 2-aminoethanol.

When HO-W-R^(f) is used, it is advisable to proceed according to the Mitsunobu variant (cf. Synthesis (1981), 1 and J. Med. Chem. 33 (1990) 187).

In the cyclic hydroxylimides X, D is, for example, C₂ -C₃ -alkylene, C₂ -alkenylene or a 5-membered or 6-membered ring containing up to three double bonds and, if required, a nitrogen atom, for example phenylene, pyridinylene, cyclopentylene, cyclohexylene or cyclohexenylene. For example, the following substances are suitable: ##STR9## The reaction of the compounds IX with the hydroxylimides XIII is advantageously carried out in the presence of a base. Suitable bases are in principle all those which are capable of deprotonating the hydroxylimides XIII without attacking the imide system. These are in particular the nonnucleophilic bases. Examples are mineral bases, such as alkali metal and alkaline earth metal carbonates, and alkali metal and alkaline earth metal bicarbonates, and organic bases, such as aliphatic, cycloaliphatic and aromatic tertiary amines. Mixtures of these bases may also be used.

Examples of individual compounds are the following bases: sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate, barium carbonate, the bicarbonates of these metals, trimethylamine, triethylamine, tributylamine, ethyldiisopropylamine, N,N-dimethylaniline, 4-N,N-dimethylaminopyridine, diazabicyclooctane, diazabicycloundecane, N-methylpiperidine, 1,4-dimethylpiperazine, pyridine, quinoline, bipyridine and phenanthroline. The economical bases sodium carbonate and potassium carbonate are preferred.

The base is added in general in equivalent amounts up to an excess of 5 equivalents, based on the hydroxylimide. A larger excess is possible but has no additional advantages. It is also possible to use a small amount of bases. However, from 1 to 3, in particular from 1 to 2, equivalents, based on the hydroxylimide XIII, of a base are preferably used.

It is also possible to use nucleophilic bases, for example alkali metal and alkaline earth metal hydroxides, in particular sodium hydroxide and potassium hydroxide. In this case, it is advantageous to use the base in equivalent amounts, based on the hydroxylimide XIII, in order to avoid nucleophilic attack by the hydroxyl ions on the carbonyl function of the imide group.

The starting compounds XII are advantageously reacted with the hydroxylimides XIII in a solvent which is inert under the reaction conditions. Advantageous solvents are, for example, polar aprotic solvents, such as dimethylformamide, N-methylpyrrolidone, dimethyl sulfoxide, sulfolane and cyclic ureas. The amount of solvent is in general not critical.

The reaction of the starting compounds XII with the hydroxylimides XIII can also be carried out using phase transfer catalysis. In this case, solvents which form two phases with water, preferably chlorohydrocarbons, are used. Suitable phase transfer catalysts are the quaternary ammonium and phosphonium salts, polyethylene glycol, polyethylene glycol ethers and crown ethers usually used for such purposes, as described in, for example, Dehmlow et al., Phase Transfer Catalysis, pages 37-45 and pages 86-93, Verlag Chemie, Weinheim 1980. The phase transfer catalysts are advantageously used in amounts of from 1 to 10, preferably from 3 to 5, % by volume, based on the volume of the reaction mixture.

The reaction of the starting compounds XII with the hydroxylimides XIII is carried out in general at from 0° to 140° C. preferably from 20° to 100° C., in particular from 40° to 80° C. In an advantageous procedure, the hydroxylimide XIII is initially taken together with the base in the solvent, and the starting material XII is metered into this solution. It may prove advantageous if the hydroxylimide is added at a lower temperature, for example at up to 50° C., and the reaction mixture is heated to the actual reaction temperature only after this addition.

As a rule, the reaction is carried out at atmospheric pressure or at the autogenous pressure of the solvent.

After the end of the reaction, water is advantageously added to the cooled reaction mixture, the resulting hydroxylamine derivatives XIV separating out as crystalline solids or as oils. The hydroxylamine derivatives obtained in this manner can, if desired, be further purified by recrystallization or by extraction.

The hydroxylamine derivatives XIV may be stored or immediately converted into the hydroxylamine derivatives X having a free amino group. This conversion can be carried out by conventional methods, as described in, for example, DE-A 36 15 973 and the publications cited therein. The process according to DE-A 36 15 973, in which the hydroxylamine derivatives X are liberated by means of ethanolamine, is preferably used. It is also possible to liberate the hydroxylamine derivatives X with the aid of other bases, such as aqueous mineral bases, amines, hydrazines, hydroxylamines or aqueous acids.

The hydroxylamine derivatives X can be isolated from the reaction mixtures obtained by these processes by means of conventional working up methods, for example by extraction or by crystallization. To increase the tendency of these hydroxylamine derivatives to crystallize, it may also be beneficial to convert them into their salts with mineral acids or organic acids. For this purpose, dilute solutions of these acids are generally reacted with the hydroxylamine derivatives, advantageously in equivalent amounts. As in the case of the hydroxylamine derivatives having a free amino group, the resulting hydroxylammonium salts can be further processed directly to give the herbicides of the formula II or, if desired, can be stored.

The cyclohexenone derivatives II may be obtained as isomer mixtures in the preparation, both E/Z isomer mixtures and enantiomer or diastereoisomer mixtures being possible. The isomer mixtures can, if desired, be separated by the conventional methods, for example by chromatography or by crystallization.

Suitable herbicidal active ingredients (A) are both the pure enantiomers II and racemates or diastereoisomer mixtures of cyclohexenone derivates II.

The cyclohexenone derivatives II may be represented in a plurality of tautomeric forms, all of which form the subject of the invention.

are known from the literature (cf., for example, DE-A 22 23 894, DE-A 24 33 067 DE-A 25 76 251, DE-A 30 04 770, DE-A 32 46 847, BE-A 868 875, BE-A 858 618, EP-A 054 715, EP-A 248 968, EP-A 323 127 and U.S. Pat. No. 4,753,673).

The 2-(4-hetaryloxy)- and 2-(4-aryloxy-phenoxycarboxylic acid derivatives III may contain one or several centers of asymmetry. They are effective as racemates, as they are obtained in most methods of manufacture, but may if desired be prepared as pure isomers, or separated, by conventional methods.

Both the racemates and the pure isomers control unwanted plants from the Gramineae family. The tolerance by crop plants of these substances varies from commercially acceptable to unacceptable, depending on the substituents and application rate.

Specific examples of herbicidal 2-(4-hetaryloxy)- and 2-(4-aryloxy)-phenoxycarboxylic acid derivatives of the formula III whose crop plant tolerance can be improved by substituted thiochromenones I are listed in Table 10 below:

Herbicidal active ingredients and safeners may be applied together or separately to the leaves and shoots of the crop plants and unwanted plants. It is, however, preferred to ply the herbicidal active ingredients and safeners simultaneously. If the herbicidal active ingredient and safener are applied separately, the safener is preferably applied first.

The safener and the herbicidal active ingredient may be formulated together or separately as suspensions, emulsions or solutions, and used as such to prepare spray liquors.

Safening effects are also achieved by treating the seeds of the crop plants or the seedlings with the safener prior to sowing or transplantation. The herbicidal active ingredient is then applied alone in conventional manner.

When the active ingredients are used for treating seed, amounts of from 0.1 to 10, and preferably from 1 to 2, g per kg of seed are generally required.

When the safener is used in seed swelling or for treating seedlings, solutions are preferably used which contain the safener in concentrations of from 1 to 10,000, and especially from 100 to 10,000, ppm.

Usually, the amount of safener I and herbicidal compound I or II varies from crop to crop; the ratios can vary over a wide range. They depend on the structure of the cyclohexenone derivatives II or the hetaryloxy- and aryloxyphenoxyacetic acid derivatives III, of the substituted thiochromenones I and the crop in which the compounds are applied. Suitable ratios of herbicidal active ingredient to safener-active thiochromenone I are from 1:10 to 1:0.01, preferably from 1:4 to 1:0.1.

The agents according to the invention, or the herbicidal active ingredients and safener if applied separately, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), dispersions, emulsions, oil dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used.

For the preparation of solutions, emulsions, pastes and oil dispersions to be sprayed direct, mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, further coal-tar oils, and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons such as toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, methanol, ethanol, propanol, butanol, cyclohexanol, cyclohexanone, chlorobenzene, isophorone, etc., and strongly polar solvents such as N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone and preferably water are suitable.

Aqueous formulations may be prepared from emulsion concentrates, pastes, oil dispersions, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes and oil dispersions the ingredients and/or safeners as such or dissolved in an oil or solvent may be homogenized in water by means of wetting or dispersing agents, adherents or emulsifiers. Concentrates which are suitable for dilution with water may be prepared from active ingredient and/or safener, wetting agent, adherent, emulsifying or dispersing agent and possibly solvent or oil.

Examples of surfactants are: alkali metal, alkaline earth metal and ammonium salts of aromatic sulfonic acids, e.g., ligninsulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl and alkylaryl sulfonates, and alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexadecanols, heptadecanols, and octadecanols, salts of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ethers, ethoxylated isooctylphenol, ethoxylated octylphenol and ethoxylated nonylphenol, alkylphenol polyglycol ethers, tributylphenyl polyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignin-sulfite waste liquors and methyl cellulose.

Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients and/or safener with a solid carrier.

Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. Examples of solid carriers are mineral earths such as silicic acids, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate; and ureas, and vegetable products such as grain meals, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.

The formulations contain from 0.02 to 95, and preferably 0.5 to 90, % by weight of active ingredient and safener.

The herbicidal agents may contain, in addition to the antagonistically effective thiochromenones I and the herbicide from the group of cyclohexenones II or the (hetaryloxy)- or aryloxyphenoxycarboxylic acids III, further herbicidal or growth-regulating active ingredients of different chemical structure without the antagonistic effect of the substituted thiochromenones I being affected.

Example demonstrating the biological action

The influence of various representatives of the herbicidal agents according to the invention, or combinations consisting of herbicide and safener, on the growth of crop and unwanted plants compared with the influence of the herbicidal agent on its own is demonstrated by the following examples from greenhouse experiments:

The vessels employed were plastic flowerpots having a volume of 300 cm³ and filled with a sandy loam containing about 3.0wt % humus. The seeds of the test plants were sown separately, according to species, and then moistened. The vessels were then covered with transparent plastic lids until the seedlings had germinated and the plants had taken root.

For the postemergence treatment, the plants were grown, depending on growth form, to a height of 3 to 20 cm before being treated with the compounds, which were suspended or emulsified in water and sprayed through finely distributing nozzles.

The following cyclohexenone derivative II was used by way of example: ##STR51## All safening compounds were formulated for postemergence treatment in a mixture consisting of 80wt % of cyclohexanone as diluent and 20wt % of a surfactant (Emulphor EL*)) containing 10wt % of active ingredient.

For comparison purposes, the herbicidal active ingredient was formulated as a 10 to 20wt % emulsion concentrate and used in the spray liquor together with that amount of solvent system with which the safeners were applied. The solvent was prepared by mixing the active ingredient with a solution of 93wt % of xylene and 7wt % of Lutensol AP-8**.

After the active ingredient mixtures had been applied, the test plants were cultivated in the greenhouse--heat-loving species at about 18° to 30° C., and those from milder climates at about 10° to 25° C.

The experiment was run for 3 to 5 weeks. During this period the plants were tended and their reactions to the treatments assessed.

The damage caused by the chemical agents was assessed on a 0 to 100% scale compared with untreated plants--0 denoting no damage and 100 complete destruction of the plants.

The improvement in the tolerance by crop plants from the Gramineae family, such as wheat and Indian corn, of herbicidal cyclohexenone derivatives II achieved by pyrido[2,3-d]pyrimidines I is apparent from the following Table B.1: *) ethoxylated castor oil **) nonionic surfactant based on alkylphenol polyethylene glycol ether
